A suspect has been arrested in the 2012 stabbing death of a homeless woman in Santa Rosa, police said Wednesday.

Jessy Zetino, 22, of Santa Rosa was taken into custody Tuesday after DNA evidence tied him to the slaying of 24-year-old Michela Wooldridge, police said.

Wooldridge, who had recently moved to Santa Rosa from Humboldt County, was found lying in the driveway of a business on the 1200 block of Fourth Street about 5:20 a.m. on Nov. 1, 2012. She had been stabbed in the chest numerous times.

The motive for the attack hasn't been established, and there were no signs that Wooldridge had been robbed or sexually assaulted, police said. The two did not appear to know each other before the slaying, officials said.

Zetino frequented the area where Wooldridge was killed and had been at a party in the area on Halloween, the night before she was found, authorities said. He is being held without bail at Sonoma County Jail.
